Oh so lovingly called the 'Google image search pack', Life Abounds is compiled from many different images I've found, yes, searching Google, as well as a few of my own photos. It makes Minecraft scenery look truly realistic. The trees, in particular, are my favorites, as you can see the leaves, and needles, and it looks like you can reach out, an touch the bark.
I'll leave some screenshots. You should see what I mean. I hope you all like it.
